To all whom'it may concern:

Be it known that I, ARTHUR Enivns'r JER- RAM, a subject of the King ofthe United Kingdom of Great Britain and Ireland, re- 5 siding atLeicester, in the county of Leicester, England, have invented certainnew and useful Improvements in Ga'ging Mechanism for Shoe-SewingMachines; and I do hereby declare the following to be a full, clear, andexact description 01 the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

The presen invention relates to gaging mechanism for shoe sewingmachines and more particularly to that type of sewing machines adaptedto stitch the outsole' to the welt of a lasted shoe. shoes the outsoleprojects varying distances beyond the upper as in the so-calledBaltimore edge shoes, wherein the sole at the outer side of the ballportion projects farther from the upper or is wider than it is at thetoe portion or at the inner side of the ball of the shoe. In such shoesthe shank 5 portion of the sole is usually, sewed with a close edge,that'is to say, the edge of the sole projects but little beyond theupper, while around the forepart the sole projects at a greater andusually at a varying distance '0 from the upper. In securing the outsoleto the welt it is desirable that the seam of stitches which unites theoutsole to the welt should lie close to the edge of the sole, especiallyaround the iorepart, while in the 5 shank it is sometimes the practiceto have the stitches of greater length and to locate the seam fartherfrom the edge of the sole. Various gaging mechanisms have been in ventedfor use in connection with the Good- 0 year rapid stitcher, all ofwhich, however, were adapted for use in connection with a machine whichemployed a stationary work support or table and a movable presser footfor holding the work upon the table during 0 the sewing operation. Myinvention, however, is intended to be used in connection with a shoesewing machine in which. the

V work supporter table is movable toward and from a cooperating presserfoot, and the 0 specific embodiment of my invention illustrated theaccompanying drawings is shown in connection with the outsole stitcherillustrated and described in Letters Patent of the United States grantedto French and 5 Me er, October 8,1889,No.$12,-703. v

In some forms of The present invention consists in the devices andcombinations of devices hereinafter described and particularly definedin the claims.

In the accompanying drawings ing the preferred form of my invention,Figure 1 is a front elevation of a portion of the sewing machine of saidpatent provided with my improved gaging mechan1sm; F1g. 2 is aright-hand end elevation, and Flg. 3

illustrat V a plan ofmy gaging mechanism shown in connection with suchco6perating parts of said patented machine as are necessary to a fulldisclosure of my invention.

In the accompanying drawings, the work support 1 is mounted upon thework support carrying lever 2 pivoted at 3 on a stationary part of themachlne in substantially the manner illustrated and described in said"patent. The feed slide 4 mounted in a suitable guideway in a stationarypart of the machine is actuated by the feed'lever 5, which is pivoted atits outer end upon'the feed slide guide 6 and carries upon its inner enda cam roll 7 which engages acam path 8 in the feed cam disk 9. I Thefeed slide and its actuating mechanism constitute the feeding ineans forfeeding the work to the stitch forming mechanism. Feed regulating meansis provided which, in the illustrated embodiment of my IIIVGIliZlOIl,consists in the lever 10 pivoted at 11 to the feed slide, and providedwith a bolt 12 which engages the slot in the feed lever 5,

thearrangement being such that when the lever 10 is pushedrearwardly'the length of the stitches'is increased, and when thelever'10 is pulled forward the length of the.

stitches is diminished. The needle l3, and 14, looper 15, shuttle l6 andtake-up 16) are or may be the same asillustrated in said patentedmachine.

The gage of my invention is pivotally mounted the work support carryinglever 2, movable with and independently of one end of the rock shaftmounted in a bearing 19.

to or formed integral with the work fsupport.

the free end of which engages a -notch in" the end of a cotiperatinglever 21 secured in turn upon the track skate- 22} revolubly 17 in theillustrated embodiment upon. I 100' work support The gage l7,i ssecuredto evolubly rise and fall in said socket.

mounted in a bearing 23 secured to a stationary part of the machineconveniently the under side of the feed slide guide (3. In order thatthe movements of the work support shall not 'substantially' change the 3position of the gage with relation to said work support, I have arrangedthe cooperating ends of the lovers 20 and 21 so that they engage eachother apveniently upon the short shaft 27 mounted in abearing 28 securedto the bearing 29 of the main shaft 30 of the machine. A hand lever 31is secured to the connecting rod 25 so that the gage may be operated'bysuch hand lever if desired. The upper leg of the bell crank lever 26 isprovided with a socket which receives the shank of a bolt 32. In thebottom of the socket is placed a light spiral spring 33 which permitsthe bolt 32 to The head of the bolt 32 is bifurcated and to it ispivoted the end of the rod 3st whichpasses through a hole in the stud 35pivotally secured to and dependent from the lower side of the hand lever10, said rod 34 being provided with tappets 36 which consist of splitcol-.

lars adjustably secured to said rod 34 by means of bolts 37. Theposition of the gage 17 may be varied with relation to the work support1 by moving the handle 31 forward or backward, thereby through theconnecting rod 25, lever 24, rock shaft 22, lever 21, lever 20, and rockshaft 18 moving the gage to the desired position. v

The operation of my improved gaging mechanism is as follows: Theoperator will present a shoe to the machine, entering it at the end ofthe shank portion, the feed regulating lever 10 will be moved to itsrear position, thereby lengthening the stitches and causing its stud 35to engage one of the tappets 36 to move the gage l7 backward through themechanism above described so that the seam will lie at a certaindistance from the edge of the sole. As soon as the sewing of the shankof the. shoe is com leted the operator will move the feed re uatinglever 10 forward, thereby'decreasing the length of the stitches andcausing the stud 35 to engage the forward tappet 36, thereby moving thegage l7 forward and causing the seam to he closeto the edge of the sole.The operator may vary the posi tion of the seam with relation to theedge of l i i l l the sole independently of or in connection with thelength of the stitches, that is to i say, it it is desired to change theposition of the seam with relation to the edge of' the sole at any timewithout chan ing the length of the stitches, he may adjust the ,e'age bymeans of the hand lever 31 without adjusting or varying the length ofthe stitches. When the sewing of the forepart is completed the operatorwill again move the 'leed regulating lever backward, thereby lengtheningthe stitches and moving. the

gage 17 backward s'othat the seam shall lie at a greater distance fromthe edge of the sole than during the sewing of the forepart.

My invention is not limited to the specific emlmdiment thereofillustrated in the acr-mnpanying drawings, as the same may beconstructed differently or embodied in other kinds of shoe sewingmachines-without departure therefrom.

.llaving thus described my invention, I claim as new and desire tosecure by Letters Patent of the United tn'tates:--
